The Deep Line as Patrick states, consists of the following:

Posterior tibialis > interosseuos membrane > Knee capsule > adductor hiatus > intermuscular septum > femoral triangle > psoas > anterior longitudinal ligament > diaphragm > pericardium > mediastinum > parietal pleura > fascia prevertebralis > scalenes

Patrick goes on to explain how breathing plays a very important role in the function of this line and provides some excellent strategies for correction and progression.

This got me thinking…

Often times I will use the Bunkie Testing method to assess the various lines throughout the body. I wrote a piece about the Bunkie Test late last year and it can be viewed here. Kevin Neeled also wrote a piece and shot some video on how and why this testing method may play an important role in kinetic linking for hockey players. You can read that here.

As mentioned last fall, the Bunkie Test consists of tests for the following

• Anterior power line
• Medial stabilizing line
• Lateral stabilizing line
• Posterior stabilizing line
• Posterior power line

Do we truly know that we’re testing each of the above? Who knows, but based on Patrick’s article, I think we need to revisit the test and see how we can start testing the DEEP FRONT LINE. That is, the Deep Stabilizing Line. Maybe we can’t. But perhaps we can. I am not trying to reinvent the testing method here. I am simply seeing a flaw in the testing procedure and am now looking for a way to improve it. Joe Heiler of Sports Rehab Expert recently invited me to do an interview and discuss the Bunkie Method of Testing. I hope to do this interview in July so maybe I’ll have some answers by then.

Perhaps there are other ways to test this. I can’t remember off the top of my head right now so if you can think of one, make sure you let me know.

When a patient does present with “dysfunction” of this Deep Front Line, aside from attacking their breathing patterns, I progress to improving their rolling patterns as well. Generally, I will work the supine to prone rolling pattern to improve this line and specifically target the right arm / left leg or left arm / right leg combinations as needed. Carson Boddicker has written several pieces on these topics, one of which is a must read.  For an introduction, make sure you read Core Competencies. Mark Young makes a good argument about testing the roll, but personally, I think quality is more important than quantity in this case…but that’s just my opinion!

Progression from here would be to the Dead Bug tract (not dissimilar to Patrick’s videos) and onward to chops and lifts (thanks Mike) and beyond to really attack their stabilizing function. Check out Nick Tumminello’s video of the Vertical Pallof Press for anterior stabilization (to combat lumbar extension).

Lots of info to digest here and certainly plenty of hot links to click on. So thanks to Patrick, Mike, Kevin, Mark, Carson, Nick, and Perry for unknowingly being participants in this post!

See Below for details on his upcoming course:

Building the Ultimate back: from Rehabilitation to Performance

November 20 and 21, 2010 in Toronto

• 4 hours – Building the foundation
• 2 hours – Interpreting patient presentation
• 1 Hour – Preventing Back Disorders
• 4.5 hours – Rehabilitation Exercise

The above question is just one reason why I am looking forward to the 7th Interdisciplinary World Congress on Low Back and Pelvic Pain. Among other “questions”, answers (or at least directions) to the above will be addressed throughout this congress. Here’s a look at the preliminary program.

What are your thoughts on the above question?

• The data from this study came from two sources (firefighters and kinesiology students).

• The main objective of this study was to assess the relationship between the V-sit test and the plank test for torso flexion endurance.

• The pearson correlation was r=0.34 (low correlation) as well as the r-squared value. It almost seems obvious that these two wouldn’t correlate well as they are two totally different positions.

I think the main reason McGill did this study was because people were using the PLANK test in place of the V-SIT to test flexion endurance (which has plenty of data correlating poor endurance times with low back disorders).

• The moral of the story is to use the V-sit when doing your tests for flexion endurance.

• He also cautioned against “training the test” due to the high compressive loads.

I do not have an image of the V-Sit test but can send you a copy of the full article if you would like. Just reply below with your email and I’ll shoot it over.

• An inability to stabilize the pelvis while performing dynamic lower body movements (i.e. performing lunges in the weight room or skating in hockey) may result in shear forces sustained by the spine, creating a compensatory pattern of inefficient/lack of gluteal activation, muscle spasm, and undue stress on the hip joints and muscles.

Therefore, to minimize the risks to specific muscles that cross this joint, we must maximize the integrity of the slings that cross it. Four myofascial slings are involved here, and they include:

• Posterior oblique sling – located across the back from gluteus maximus, through the thoracodorsal fascia, and up to the latissimus dorsi.
• Anterior oblique sling – in the front of the body from the external oblique, through the anterior abdominal fascia, to the contralateral internal oblique and the adductor musculature
• Longitudinal sling – from the peroneii/fibularis group in the lateral lower leg, up the biceps femoris, the sacroiliac ligaments, through the deep thoracodorsal fascia, and up the erector musculature
• Lateral sling – containing the PRIMARY frontal plane stabilizers for the hip joint – the gluteus medius, tensor fascia lata, and the lateral stabilizers of thoracopelvic region (i.e. quadratus lumborum)

Therefore, to assess and correct one’s risk for hip and groin injuries, it would be prudent to test the integrity of these slings and their myofascial components through such testing procedures as the BUNKIE TEST.

One of the most important tenets in minimizing these injuries is the ability to CONTROL and STABILIZE this region while power is being generated. We want loads to be generated THROUGH THE JOINT and not to it!

Other considerations include ADDuctor to ABDuctor strength ratio, hip static and dynamic mobility, and joint centration.
